La Bimba di Satana on AllMovie

When the daughter and wheelchair-bound brother of a recently deceased aristocrat are placed in the care of a lecherous nun, the atmosphere around a remote Italian castle becomes thick with dread and debauchery in director Mario Bianchi's masterpiece of Euro-sleaze. Antonio is the latest in a long line of wealthy landowners. A merciless brute who abuses women, steals his brother's pain medication, and buries the rotting corpses of anyone who dares cross him deep in the cellar, Antonio is husband to insatiable nymphomaniac Maria. As the film opens, Maria has died. But this is only the beginning of the abhorrent events about to unfold in the castle, because the nun responsible for bathing her daughter and handicapped brother soon becomes overtaken with a dark sexual urge that leads to commit the ultimate act of sacrilege, and the once-innocent daughter embarks on a frenzied rampage of sex and murder after becoming possessed by the vengeful spirit of her late mother.
